The project's root directory stores a configuration file for nginx: wmt.conf.default.
It should be changed appropriately: on line 5 set $ROOT "/your/path/to/wmt";.
Then you can use this file for nginx server configuration:
ln -s ~/your/path/to/wmt/wmt.conf /your/nginx/installation/servers/

To build the project use Grunt. Installation of Grunt's command line interface (CLI) globally can be done with the following commands:

sudo apt-get npm

sudo npm install -g grunt-cli

The project is configured with a package.json and a Gruntfile.js, it's very easy to start working with Grunt:

Go to the project's root directory.

Install project dependencies with npm install.

Run Grunt with grunt.

Tests

To run tests, do python -m unittest -v testmain in the directory pub/py/
Currently, the following functions have test coverage:

analyse() - comparison of its result with the presaved result in a file testwl-a.json

save() - checking that save function generates a file with correct name

findNode() - checking that found node with findNode function has correct id

findTask() - checking that found task with findTask function has correct id

findEdge() - checking that found edge with findEdge function has correct id

dict2text() - comparison of its result with the presaved result

Usage of a tool

Workflow Design

First, click new workflow on the top of the page.

Then, create a graph of a workflow: add nodes and datastores using buttons add datastore and add node;
connect them using button add links, when it is pressed сlicking on the first then the second nodes adds an edge between them.

Add tasks into the nodes: choose a node;
